Training: Java Web Services using JAX-WS and JAXB

In this practice oriented training course the participants learn how to build Java Web Services by using the Java Web Services Standards JAX-WS, JAXB and JWS Metadata.

Course Content

Web Services Basics

Java API for XML-Based Web Services JAX-WS

• Related specifications: JAXB, SOAP, WSDL, WS-I Basic Profile 1.1, Annotations, JSR 109, Web Services Security (JSR 183)
• WSDL to Java and Java to WSDL Mapping
• Building clients with generated stubs
• Asynchronous clients with callback or polling
• MessageContext and WebServiceContext
